Understanding Lab Tests for Hyperviscosity Syndrome
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Hyperviscosity syndrome is a serious medical condition characterized by abnormally thick blood that can impair circulation and oxygen delivery throughout the body. This condition can be caused by various underlying disorders including blood cancers like leukemia, polycythemia vera, and macroglobulinemia.
Recommended Test
Viscosity, Serum
This is the primary diagnostic test for hyperviscosity syndrome. It directly measures the thickness and flow properties of blood serum. Elevated viscosity levels confirm the diagnosis and help determine the severity of the condition. This test is essential for monitoring treatment effectiveness and can help identify underlying causes such as leukemia, polycythemia vera, and macroglobulinemia.

Diagnosing Hyperviscosity Syndrome
While symptoms such as headaches, vision changes, and bleeding may suggest hyperviscosity syndrome, a definitive diagnosis requires direct measurement of blood thickness through specialized laboratory testing. Early detection is crucial as this condition can lead to serious complications including stroke, heart problems, and bleeding disorders.
Understanding Your Results
Normal blood viscosity allows for smooth circulation throughout the body. When viscosity is elevated, blood becomes thick and flows poorly, potentially causing symptoms and complications. Your healthcare provider will interpret your results in the context of your symptoms and may recommend additional testing to identify the underlying cause.
Important Considerations
